moth
Grain Moth
A tiny buff-colored moth whose larvae tunnel invisibly inside individual kernels of stored grain, hollowing them out from within.

A plain grey-brown moth whose larvae tunnel through beeswax honeycomb, spinning silk webbing as they feed, making it a well-known pest of beekeeping operations.
moth

Hovering at flowers with a blur of wings and a long uncoiling tongue, the hummingbird moth is easily mistaken for a tiny hummingbird. These plump, fast-flying hawk moths feed on nectar in broad daylight.
moth
Winter Moth
A small tan-brown moth unusual for flying in the cold of late autumn and early winter, with strongly dimorphic sexes: fully winged males and flightless, near-wingless females that climb tree trunks to lay eggs.
moth
Polyphemus Moth

A large, richly textured moth with deeply scalloped, russet-brown wings that fold into an uncanny dead-leaf silhouette, one of the most convincing leaf mimics among European moths.

A moth with a striking split lifestyle: winged, drab gray-brown males fly to seek out flightless, grub-like females, while the ornate caterpillars sport dense tufts of colorful bristly hair.
moth
Bogong Moth
A modest brown, mottled moth famous for its extraordinary mass seasonal migration across thousands of kilometers to cool alpine caves in the Australian mountains, forming one of the largest known insect migrations by biomass.

One of the largest and most spectacular silk moths in the world, with pale yellow-to-red wings and extraordinarily long, ribbon-like tails on the hindwings.
moth
Indianmeal Moth
A small moth with two-toned, coppery-and-gray wings whose caterpillars spin silken webbing through stored grain, cereal, and dried fruit.

A small tussock moth with striking sexual dimorphism: rusty-orange, day-flying males with feathery antennae contrast with flightless, grub-like grey females that never leave their cocoon to lay eggs.
